<P>PROBLEM TO BE SOLVED: To provide interpolyamide fiber that has high strength, a high modulus and high heat resistance, is minimally degraded in physical properties through moisture absorption and is good at melt spinning property. <P>SOLUTION: Interpolyamide fiber comprises: (a) 50 to 95 mol% of a constitutional unit obtained from an equimolar salt of 4-12C aliphatic diamine and terephthalic acid; and (b) interpolyamide having relative viscosity measured in concentrated sulfuric acid at 30°C of 1.0 to 4.0 and including 50 to 5 mol% of a constitutional unit obtained from 11-aminoundecanoic acid or undecane lactam. <P>COPYRIGHT: (C)2012,JPO&INPIT |
